Manual segmentation of 129 x‐ray CT transverse slices of a living male human has been done and a computerized 3‐dimensional volume array modeling all major internal structures of the body has been created. Each voxel of the volume contains a index number designating it as belonging to a given organ or internal structure. The original x‐ray CT images were reconstructed in a 512×512 matrix with a resolution of 1 mm in the x , y plane. The z ‐axis resolution is 1 cm from neck to midthigh and 0.5 cm from neck to crown of the head. This volume array represents a high resolution model of the human anatomy and can serve as a voxel‐based anthropomorphic phantom suitable for many computer‐based modeling and simulation calculations.
